PDF2IMG Color Management Enhancements

PDF2IMG has always been a top of its class PDF rendering tool, featuring excellent performance, a wide range of supported bitmap formats and high fidelity output with user adjustable controls such as smoothing options for text, images and line art.  But, recent enhancements have extended PDF2IMG‘s feature set even further beyond the typical rendering tool.

As anyone in the print or imaging business will tell you, one of the most difficult challenges they face is maintaining consistent color across a document’s life cycle, from its creation within an authoring application to its final rendering on a printer or screen. Heck, because of the way that the brain perceives color, even two people looking at the same image on the same screen don’t always agree on what they see. Was that a black and blue dress or a gold and white dress? Me? I see the dress as gold and blue. Because every device (printer, monitor) represents color in its unique way and is constrained by the color model that it uses, it’s imperative that consistent rules are applied when a document transforms mediums and color models.  To help in this effort, various organizations have created standards – foremost being the International Color Consortium’s development of ICC profiles.
With its latest release, v2.4P1j, PDF2IMG has extended its prior color management features to include additional options for color profiles. Applications that use the PDF2IMGLIB or the PDF2IMG command line program can now:

  • assign color profiles to uncalibrated DeviceCMYK, DeviceRGB and DeviceGray elements within the PDF
  • specify a color profile for the output conversion
  • embed the output profile in the output image format (for those formats that support embedding)
  • access and use the profiles embedded in a PDF’s OutputIntent dictionary
  • specify a rendering intent (perceptual, relative, saturation, absolute or profile) to be used for colors that are outside the gamut of the target color model

These features are all made possible because PDF2IMG is based on the Adobe PDF Library SDK, the same full featured PDF toolset that powers Adobe Acrobat.
